lAp'p1n2ation led January 11, 1915. -Serial No. 1,487.

To all whom t may concern :v`

Be it known that we, ARTHUR C: MASON and ALFRED T. STURT,` citizens of the United States of America, and residents of the city of Flint, county of Genesee, State of Michigan, have-jointly invented certain new and useful- Improvements in Antifriction Wheell Bearings; and we do hereby declare the foland exact description thereof.

The invention relates to improved anti friction bearings for wheels adapted foruse Une ofthe .objects of ourinvention 'is to construct an efficient, strong and yet inexpensive anti-friction bearing for wheels which maybe assembled to any shaft Without modifying or altering'the construction of the shaft. f,

Another object is to rovide an anti-friction bearing between tile hub lof the wheel and some fixed part ofthe mechanism other thanthe shaft.

AnotherA object is to 'provide a construction which can be readily assembled and dismounted.

Other objects will appear from the following description and claims.

The invention consists in the yarrangement, construction and combination of parts as will be hereinafter described and pointed out in the claims.

Referring to the drawings; Figure 1, is a plan View partly in' horizontal section through the center of the wheel and coperating parts, the hub of the wheel being shown in plan. Fig. 2, is a longitudinal section through the'center of the hub and co acting brake-flange and axle housing, showing the anti-friction device applied thereto7 the shaft being illustrated in elevation.

In the drawings like reference characters indicate likeparts. 1

In the particular embodiment of our invention, as disclosed it is applied tothe rear axle construction, but the broad invention which 50Obe also applied to the front wheels.

consists in the anti-friction bearing placed between the surface of the hub of the wheel and any fixed part other than theshaft, may

A is the axle shaft, vB the shaft housing, C

' of the wheel upon the Outer end of the the brake-flange, D the wheel h ub, E the spokes, F the rim and G the tire. A flange concentric to the shaft and hub is secured to the housing by'rivets 10 and the spokes are secured to the hub by bolts in the usual way. Surrounding the flange is a spring seat 11 which is prevented from longitudinal movement by a seat 12 in the lflange and the collar 14. The outer end of the shaft is conical in shape as shown,

and the hub of the wheel is constructed to nicely lit over the conical end thereof, and is Secured thereto by the key 13. The hub ex tends a Substantial distance inwardly and is preferably case-hardened at its inner end to form a suitable bearing surface for the antifrictionbearings. A flange 15 projects outwardly from the housing and is concentric with the axle and with the hub and it forms an-annular recess 16 between it and the hub when the wheel is in place within which Vrecess is fitted an ordinary anti-fric- -tion bearing as shown` consisting of the rolle-rs 20 inc'losed by circular disks 21 and by a ring or bushing of steel 22, said disks and bushings forming a casing for the rollers 20. This concentric steel ring or bushing is held in place by a set screw 23 which is screwed into a hole in the concentric projecting flange 15 of the brakeflange. The hub is smooth on its outer sur- -face and a flanged plate is held thereto by a nut 31 which is screwed to the end of the axle. Screw-threads are provided on the outer edge of the flange and screwed :thereto is'the usual protecting cap or casing 32. A felt washer 35 is fitted around the shaft between a metalwasher 36 -and the inner end of the hub. A vfelt washer 37 is fitted around the hub and held between the portion 38 of the brake casing and the outer end of the flange 15 which projects from the fixed housing.

In assembling the wheel, the felt washer 35 and the metal washer 36 are first placed in position on the shaft. The felt washer 37 is fitted over the end of the hub and the anti-friction bearing is then fitted over tb endof the hub and the wheel is then place' shaft and prorerly keyed thereto. The set screw 23 is then Patenten nee. 7, lola.

put place so iasfto'lengage with the lsteel bushing of the antifrition bearing s0 as t0 f hold the bushing in a' fixed position. f'lhetomobile and the torquewill be transmitted' to the hub of the vvheel. As the nest of antifriction rollers is situated between the outer surface of the hub and theiixedl'ange. secured to. the shaft housing,'it is seen that 1an-ample and eiiicient anti-friction roller .bearing Will operate against the inner steel [i case-hardened surface of the hub.v

bushing on the brakeflange and the ,outer our invention'in' the accompanying drawlings, it `is to ybe understood that said drawingsare merely illustrative, and-that We are v. 'not confined to What is there shown and herein described, in connectionV therewith,-v

eXcept 'as may be specifically set forth in the claims. K

vHaving now described our invention, what i for holdin We claim as new and desire to secure hv Let- .ters Patent, is z 1. In a device of the class described, a shaft, a Wheel mounted thereon, having an extended hub, a fixed ange surrounding the jhub, an anti-friction device provided with a casing betweenthe hub and the Hange, means the casing of the anti-friction device in p ace.

:2. ,In a device of the class described, a shaft, a Wheel mounted thereon having'an Iextended hub, a shaft housing, a flange s'ecured to said housing and surrounding said hub, an anti-friction device between the` ange and hub, 'a casing for holding said anti-friction device in place, means to hold the casing in place and an anti-friction Washer-between the end of the flange and the side-of the Wheel. While We havefshovvn certain features o f :In Witness/'whereof We have hereuntoset our hands at the borough of Manhattan, city and State-of New York, this 8th. day of Januaryt 1915. y
